Given the circumstances (extreme cold) I would also suspect jamming by
overwind -- when the grease on the levers beside the battery chamber gets
thick, they can't operate to stop the wind when they should.  As a result,
the gears "overwind" and jam the shutter.  In this case, though, the meter
will usually operate.  Warming will have no effect -- only disassembly of
the gear train and subsequent removal of the excessive lubrication on those
levers will correct the problem and prevent a repeat performance.

Another possibility (though not usually related to cold) would be if the MD
switch (unlike other OM's, it's located beneath the mirror) hung up the
inertia retard that slows the mirror lifting to provide time for the program
mechanism to operate.  This is another malady that would need professional
attention for a reliable solution.
